These are circuits that you can build at home, which may help solve
some small problems by building simple gadgets. That also will help you
learn and improve your skills and knowledge.
It is important to learn analog and power electronics and then work on
digital and Microcontroller. Then you will be able to interface the
chip to the real world in a realistic manner and write frugal and lean
code.
There are some things that should not be done by code, and some things
which if done with code can save a lot of chips and cost. So to
be pragmatic in your approach, you should learn at home even as a
student, on how to solve problems by building simple equipment.
